On a smartphone, the use of a GPS can be done with or without internet. A network connection is useful for software updates or simply for downloading additional cards. On the other hand, the disadvantage on a smartphone and that it consumes a lot of DATA and that the bill can be salted if one does not have a subscription in full internet. From a foreign country, it is highly recommended to check the type of your internet subscription for your smartphone. The slightest use of GPS in network mode can be very painful on arrival for your wallet.
The offline mode obviously does not make it possible, for example, to take advantage of users' signage in real time as on Waze. But the information remains relatively accurate if we took care to download the latest update of its application.
Among the offline GPS some are in paid form.
The principle is simple. Just download the cards from your favorite app to your phone SD card. A smartphone has a GPS chip that works without internet. It can be disabled but to use a GPS is essential because it communicates your position on the cards you use off-network. Charging cards beforehand assumes that you have enough free space on your SD card. Everything is cached so sometimes the amount of data is large. As a precaution, it is good to disable your network connection when you connect your GPS offline.
